Mt Siple Vulkan (Marie Byrd Land, West-Antarktis) Tätigkeitsupdate: mögliche Dampfwolke am 20. Juni 2012 entdeckt

Mt Siple volcano in Antarctica might have become active and produced a steam plume recently detected on satellite imagery. The latest Smithsonian activity report mentions:
"Infrared imagery from the Metop satellite showed a possible rising steam plume from the area of Siple on 20 June. The imagery, as interpreted by Mark Drapes, indicated that the volcano was about -22 degrees Celsius, about 6 degrees warmer that the surrounding landscape, and the base of the plume was about -55 degrees Celsius.
